Ok, so Venus isn’t an extrasolar planet (exoplanet), but I thought this would be a cool thing to try. A while ago I put together a time-lapse movie of the 2012 Transit of Venus. More recently, during a public talk on exoplanets, I saw a video someone had made to demonstrate the transit method used to detect planets around other stars. The video looked a bit like my time-lapse, except that it was a simulation. I thought, “why not try to get a real light curve from my transit footage?” Continue reading
Fix it in post. It’s a common phrase in photography and one which is widely recognised as landing you in hot water if you’re not careful. Fix it in post-production, fix it after the fact. “Hm, I’ll just fix that in post.”

For 7 hours I followed the sun across the sky just by nudging my camera mount this way or that. As a result the sun was in a different place in every photo.

On 6 June 2012, Venus passed directly between Earth and the Sun. This ‘transit’ won’t happen again until 2117, so I’m happy that I got some photos of it! I was asked to write a few words on my experience for the August 2012 issue of the AAO Observer newsletter, so in lieu of rehashing the same story, here’s what I wrote for the article.
